Chartopia

Chartopia turns random tables into small composable programs. Users can search public charts, roll them directly, or create their own with Markdown, equations and a template language. One chart may call another, collect several results and accept input variables, allowing a single button to generate a character, location or event from many dependent tables. Collections, embeds and the newer developer API make those generators reusable outside the main browsing interface. This is particularly useful for solo-roleplaying or games whose procedures rely on many oracles.

The library is community-published, so popularity does not establish permission or accuracy. A table copied from a commercial book may be available without the rights needed for reuse, and a complicated generator can hide assumptions that affect probability. The main site also returned an automated-access error during this review, although current developer and community pages remained visible. Authors should test distributions, cite original creators and keep local copies of vital content. Chartopia is powerful infrastructure for random procedures, but curation remains the user's responsibility.
